>> Importantly, if you look at any large amount of mass - at least everything we've looked at - the total electric charge is near 0. > This is the assumption made. It’s not an assumption. It’s measured and modeled, and if it didn’t hold in general then so many things we see around us would simply not work. Nothing we have seen behaves in a way that would look like a significant electric force imbalance. On a galactic scale, electric storms are nothing. They’re a blip. Everything we see interacts as if gravity is the only thing that matters. To say we should consider this to not be the case requires strong evidence.
